Description

  The present invention relates to a peeling knife suitable for peeling fruits such as apples and pears or potato straws.
The present applicant has previously proposed a peeling knife that is used to form a round peel hole in a metal plate, form a blade around the peel hole, and peel a fruit or the like with this blade (Patent Literature). 1). The present invention relates to an improvement of the previously proposed skinning knife.
JP-A-2005-87537
  Since the previously proposed skinning knife has a structure in which a round peel hole is formed in a metal plate and a blade is formed at the periphery of the peel hole, the blade is located on the same surface as the plate surface of the metal plate. Therefore, when the shape of the fruit is a sphere, if the radius of curvature is too large compared to the radius of the peeled hole, the depth that the fruit enters the peeled hole becomes shallow, and there is a disadvantage that the bite into the fruit etc. is shallow. . Furthermore, if the object to be peeled is cylindrical or conical like carrot, for example, its side is almost straight, so if that side completely crosses the peeled hole in its radial direction, The blade cannot engage with carrots.
  The object of the present invention is to eliminate these disadvantages and to provide a peeling knife having a simple structure.
The peeling knife according to the present invention is
A metal plate in which a peeled hole having at least an arc part and an opposing edge part facing the first arc part on the inner peripheral edge is formed;
A protruding portion formed by protruding from the metal plate so that a peripheral press region including at least the arc portion of the peeled hole forms a weight surface;
A blade having a surface cut parallel to the metal plate at the tip of the protrusion,
The height of the opposing edge from the plate surface of the metal plate is made lower than the height of the blade.
  According to the present invention, the arc portion forming the periphery of the peeled hole protrudes from the plate surface of the metal plate, and the blade parallel to the metal plate is formed at the tip thereof, facing the arc portion of the periphery of the peeled hole. Since the facing edge portion is lower than the blade, the surface layer portion of the target object to be peeled from the arc portion to the facing edge portion can contact the blade at an angle. As a result, even if the shape of the object is not spherical, the blades will well bite into the surface layer of the object and the skin will be easy to peel off.

Two round peel holes with a diameter of about 22 mm are formed on a stainless steel plate having a rectangle of about 90 × 60 mm and a thickness of about 0.5 mm with a position of about 10 mm shifted, and the two are joined to form a long hole. A protrusion having a folding line on the outside of the long hole is formed, and the formation position of the long hole is protruded from the position of the plate surface of the metal plate to either one. A blade is formed by cutting the edge of the protruding long hole into a flat shape. The blade is heat treated to give the blade characteristics.
Triangular protrusions are formed on both sides of the short side of the metal plate. In addition, a handle is attached to the long side of the metal plate to complete.
  1 to 4 show an embodiment of a peeling knife according to the present invention. In the figure, 10 indicates a metal plate. This metal plate can be made of, for example, a stainless steel plate having a thickness of about 0.5 mm. In this embodiment, the metal plate 10 has a rectangular shape, the dimension W in the short side direction is about 50 to 60 mm, and the dimension L in the long side direction is about 70 to 90 mm.
  The peeled hole 12 is formed at substantially the center in the short side direction. The shape of the peeled hole 12 is such that the diameter around the two points Qa and Qb that are about 10 mm apart from each other in the long side direction at the center in the short side direction of the metal plate 10 is about 20 to 25 mm. It has an oval shape surrounded by two convex arc portions 12a and 12b and two linear portions 12c circumscribing at the same time. Such a peeled hole 12 is formed by press punching.
  After forming the peeled hole 12, the press region 13 </ b> G surrounding the peeled hole 12 is protruded from the plate surface of the metal plate 10 by a press so as to form a conical surface having a substantially constant angle, thereby forming the protruding portion 13. The bending start position of the protrusion 13 that is the outer periphery of the press region 13G is, for example, about 10 mm outside from the inner periphery of the peeling hole 12, and the protrusion angle is about 10 °. The center of the outer peripheral arc portion 13b of the press area 13G surrounding the arc portion 12b coincides with Qb. Further, the radius of curvature of the outer arc portion 13a of the press area 13G surrounding the arc portion 12a is the same as the radius of curvature of the outer arc portion 13b of the press area 13G surrounding the arc portion 12b, and the center is Qb from Qa. It is shifted to the side. Therefore, the width of the press region 13G gradually decreases from one end of the straight portion 12c toward the intersection with the extension line II-II of Qa and Qb, and the outer peripheral arc portion 13a surrounding the arc portion 12a of the press region 13G is The arc portion 12a is substantially in contact with the straight line II-II connecting the centers Qa and Qb. Alternatively, as indicated by a broken line 13a ', the radius of curvature of the arc portion 13a on the center Qa side may be increased so that the region where the press region 13G crosses the extension line is cut by the arc portion 12a. Further, the protruding portion 13 may be formed by pressing simultaneously with the punching of the peeling hole 12.
  Due to the formation of the protrusion 13, the press region 13G protrudes with a height H of about 2 mm from the plate surface of the metal plate 10 as shown in FIG. FIG. 2 shows a cross section after formation of a blade 14 described later). FIG. 3A shows a cross section taken along line IIIA-IIIA in FIG. 1 in this state. By cutting, for example, with a grinder parallel to the plate surface of the metal plate 10 as shown by the XX line, the blade 14 can be formed as shown in FIG. 3B. Thereby, as shown in FIG. 1, the blade 14 is formed in the circular arc part 12b centering on Qb of the peeling hole 12, and the extended linear part from the both ends. At this time, as shown in FIG. 2, the arc portion 12 a centering on Qa of the peeled hole 12 has a height from the plate surface of the metal plate 10 lower than H, and no blade is formed there.
In this way, the arc portion where the blade 14 is not formed has a height from the metal plate 10 lower than the height of the blade 14, so that even if the object to be peeled is cylindrical, it can contact the blade 14 at an angle. Can be skinned.
Further, since the blades 14 are formed in the arc portion and the straight portion, there is an advantage that the position of the blade 14 can be selected depending on the shape and size of the fruit or the like.
Furthermore, since the position of the blade 14 protrudes from the metal plate 10, when the blade is worn, the blade can be sharpened while keeping the metal plate 10 parallel to the grindstone.
  One short side of the metal plate 10 is formed on the same one end side of both long sides of the metal plate 10 by forming a notch of a triangle having one side on the long side and one corner positioned near the corner of the rectangle. Triangular protrusions 11 are formed on both sides of the side. The protrusion 11 is suitable for use in, for example, excising a potato bud portion. Although a blade may be formed on the inner side of the protrusion 11, a sharp blade is not necessarily required.
  Two holes 16 (FIG. 1) are formed along each of the long sides of the metal plate 10. The hole 16 is a hole for attaching the handle 17. The handle 17 is formed of a resin material having an L-shaped cross section as shown in FIGS. A boss 17 </ b> A is formed on the side surface of the handle 17. The handle 17 can be attached along the long side of the metal plate 10 by inserting the boss 17A into the hole 16 formed in the metal plate 10 and caulking the boss 17A from the back of the metal plate 10 while heating.
As described above, in the method for manufacturing the peeling knife of the present invention,
(a) A peeled hole 12 having an arc part 12b and an arc part 12a opposite to the arc part 12b in the metal plate 10, and the height of the peripheral part including the arc part 12b from the plate surface of the metal plate is the arc part. A step of forming the protruding portion 13 higher than 12a by pressing;
(b) cutting the tip of the protruding portion 13 parallel to the plate surface of the metal plate to form a blade 14 on the periphery including the arc portion 12b;
It is characterized by containing. This feature also applies to all embodiments described below.
  FIG. 6 shows a second embodiment of the present invention. In this embodiment, the radius of curvature of one arcuate portion 12a forming the peeled hole 12 is made larger than the radius of curvature of the other arcuate portion 12b. The peeled holes 12 surrounded by the arc portions 12a and 12b having different radii of curvature and the two straight portions 12c circumscribing them are substantially oval. By making the curvature radii of one and the other arc portions 12a and 12b constituting the peeled hole 12 different from each other, the straight portions 12c connecting the two arc portions are not parallel to each other. The blades 14 are formed on the non-parallel straight portions 12c and the arc portions 12b in the same manner as in the first embodiment. In addition, it is good also as a curved part which the peeling hole 12 becomes more oval instead of the linear part 12c. The peel width of the skin can be selected by changing the biting position of the skin with respect to the non-parallel blade. As a result, a user-friendly skinning knife can be provided.
  This embodiment is different from the previous embodiment in that the metal plate 10 has a circular shape, the peeled hole 12 has a shape in which two circles having different radii are combined, and the blade 14 is provided in order to improve safety when carried. The point which is provided with the cover which covers the single side | surface of the formed metal plate 10 differs greatly.
  FIG. 7A shows the bottom surface of the peeling knife according to Example 3, and FIG. 7B shows a cross section taken along the line VIIB-VIIB in FIG. 7A. In the circular metal plate 10 of this embodiment, a peeled hole 12 having a composite shape of two circles having different radii is formed. The center Qb of one of these two circles substantially coincides with the center of the circular metal plate 10, and the center Qa of the other circle is approximately in the vicinity of the circumference of the one circle. The diameter of the other circle is 10-50% larger than the diameter of the other circle. The shape of the peeled hole 12 is determined by the arc 12b of one circle and the arc 12a of the other circle defined by the synthesis of these two circles.
  A pressing region 13G surrounded by a circle that is inscribed in the extension of a straight line connecting the arc Q12a of the other circle and the center Qa and Qb with the center Qb as the center is protruded by pressing to form a protruding portion 13. . As a result, the arc 12b is positioned at the tip of the highest protrusion 13 from the plate surface of the metal plate 10, and the arc 12a is gradually lowered from both ends of the arc 12b to the plate surface of the metal plate 10. Therefore, by cutting the tip of the protrusion 13 in parallel with the metal plate 10, the blade 14 is formed on the periphery of the arc 12b.
  In the third embodiment, the outer peripheral edge portion of the circular metal plate 10 is embedded and fixed on the inner peripheral surface of the annular body 21 made of a synthetic resin material. The annular body 21 has the function of the handle 17 in the above-described embodiment. Further, in this embodiment, instead of the protrusion 11 formed on the metal plate 10 in the above-described embodiment, a plate-like protrusion 21A having a similar function is formed by extending the Qb direction extension line from the center Qa and the annular body 21. It is integrally formed at the intersection with the outer peripheral surface. The protrusion 21A has a plate shape parallel to the metal plate 10, and the tip thereof forms an acute angle in a direction away from the center Qb.
One end of a belt-like hinge 23 is integrally formed on the outer peripheral surface of the annular body 21 on the opposite side of the projection 21A in the diameter direction. A circular lid 22 having a rim 22 </ b> A having an inner diameter substantially equal to the outer shape of the annular body 21 is formed integrally with the other end of the hinge 23. In the rim 22A, notches 22a and 22b are formed at portions intersecting with the extension of the straight line connecting the centers Qa and Qb. When these notches 22a and 22b fold the lid 22 around the hinge 23 as shown by the arrow 31 in FIG. 7B to accommodate the annular body 21 in the rim 22A, the projection 21A and the hinge 23 come into contact with the rim 22A. I am trying not to. At this time, both sides of the protrusion 21 </ b> A are elastically sandwiched between both ends of the notch 22 a, and the state where the lid 22 is engaged with the annular body 21 is maintained.
The annular body 21, the protrusion 21A, the lid 22, and the hinge 23 can be integrally formed with the metal plate 10 by insert molding.
Modification 1
In Examples 1, 2, and 3 described above, the shape of the peel hole 12 is an ellipse, an oval shape, a two-circle composite, etc., and each of the peel holes 12 has a major axis and a minor axis. Alternatively, the peel hole 12 may be circular, and the blade 14 may be formed only in a substantially semicircular arc portion 12b, as shown in the bottom of the inner peripheral edge of the peel hole 12 and a cross section along the line VIIIB-VIIIB.
Modification 2
In each of the above-described Examples 1, 2, and 3, the peeled hole 12 has two circular arcs centered at points Qa and Qb as shown in FIGS. 9A and 9B by cross sections along the bottom surface and the line IXB-IXB, respectively. The blades 14 may be formed on the circular arc portion 12b and the one straight portion 12c by using an ellipse formed by the portions 12a and 12b and the two straight portions 12c circumscribing these circles.
Modification 3
In each of the above-described embodiments, the case has been shown in which the opposing edge portion facing the arc portion 12b forming the inner peripheral edge of the peeled hole 12 forms the arc portion 12a. For example, FIG. 10A is a modified example of FIGS. , 10B, a straight line portion 12d may be formed in place of the circular arc portion 12a so as to show the bottom surface and its XB-XB cross section.
